Hi, I've just started supplementing bf with formula at night as I feel my supply is low and DD is not gaining weight very quickly even on the 0.4th centile. I have the Avent bottles and teats. He takes the teat no problem and guzzles the milk in no time. I feel the flow on the teat is too high. It actually drips when the bottle is tilted. It is a size 1. Some milk even drips from the corner of his mouth as I feel he can't swallow it quickly enough.
Do all teats drip like this or is there something wrong with the ones I have? If I want a slower flow what are the choices?
Thanks
